old vehicle questions

hey guys so most of the installs i've seen are here are really nice and very clean. The thing i've noticed is that most of your guy's cars are relatively newer 1990 and later. Well i'm into four wheeling, so me and my dad are restoring a 1976 international scout terra. so here is my problem: The dash (if you'd even call it that) is way to small for anything to be molded into it. I don't know if a motorized screen would work, but I really want to mold a screen in to the dash for that perfect oem, meant to be type of look and feel. Can I add onto the dash with fiberglass material. I've read about just making the screen bezels, and most nice ones take 40 hours + , so would this dash take like a year to make if I added on with bondo and went through the sanding process.... and how would I even go about adding on to the dash anyways?? here are some pics of ripped apart interior to give you an idea:
